The achievements of 19th Century physicists stand shoulder to shoulder with those of their 20th Century successors. Physics, per se, did not exist in 1800, but a century later, physics not only existed, but was regarded as the model for all sciences. During the 19th Century, the physics that dominates current introductory textbooks was brought to completion. Electricity and magnetism, two separate domains of Nature, were united as electromagnetism; the laws of thermodynamics were established; the kinetic theory of matter was developed in its current form; and the nature of light, the crowning achievement of 19th Century physics, was demonstrated to be an electromagnetic wave. The substantive achievements were stunning. But more than the technical successes, 19th Century physicists made the subject part of the larger culture.
